Integrating hue with kyuubi

[preetsindhal]

Hi all

am trying to integrate hue with kyuubi and getting following error

raise QueryServerException(Exception('Bad status for request %s:\n%s' % (req, res)), message=message)
beeswax.server.dbms.QueryServerException: Bad status for request TOpenSessionReq(client_protocol=6, username='hue', password=None, configuration={'hive.server2.proxy.user': 'psingh'}):

testemr is the user configured under [Desktop] config of hue

    ldap_password = passwd
    ldap_username = testemr
